[filmscanners] Re: The"Pepper Grain" problem

["Arthur Entlich" <artistic-1@shaw.ca>]

Hi Martin,

I'm not going to challenge what you are seeing, as you have enough
experience to know what you are looking at.  I recall your output print
size was like 12" x 18" or so, which does require more judicious
spotting prior to printing.  My own experience is that my scans require
very little spotting if I do a reasonable job in initial cleaning of the
film prior to scanning, with my S4000+, which uses the same lighting as
the SS4000.  I usually only see a few, up to a dozen spots, which take
me at most 5 minutes to correct.  I find that for 8x 12" prints, only
the most obvious dust or dirt shows up (in printing) after sharpening.

I'm also not noticing "pepper grain" with my SS4000+ scans, although I
see it on my Minolta Dual II scans.  I do see grain if I really sharpen
the SS4000+ scans, but that's emulsion grain, not the bubbles that Roger
is finding.
